a) Numbers lying between 61^2 and 62^2 = 122
b) Numbers lying between 90^2 and 91^2 = 180
We have to find the numbers lying between the given numbers.
a) 61^2 and 62^2
61^2 = 3721
62^2 = 3844
We have to find the difference of the squares:
That is,
3844 – 3721 = 123
Numbers lying between 61^2 and 62^2 = 123 – 1 = 122
b) 90^2 and 91^2
90^2 = 8100
91^2 = 8281
We have to find the difference of the squares:
That is,
8281 – 8100 = 181
Numbers lying between 90^2 and 91^2 = 181 – 1 = 180
